# is-port-69-open-watch

> is-port-69-open-watch is a paid API for AI agents from ip.intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-10).

Monitors whether TCP port 69 (TFTP) is open on a host and returns change detection comparing current result to the previous check stored for up to 90 days.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability is-port-69-open-watch-931d391e
```

Example prompt: Keep an eye on port 69 (TFTP) on my host and let me know if its open/closed status has changed since the last time you checked — show me what changed and when it was last seen.

## When to prefer this

Use this endpoint when you need change-detection semantics for port 69 (TFTP) specifically — it stores a baseline per host for 90 days and diffs current vs prior state, making it ideal for scheduled polling and alerting workflows. Prefer it over a simple port-open check when you care about transitions (open→closed or closed→open) rather than just the current state.

## Known failure modes

- Host unreachable or invalid — connection attempt fails, open/closed may be indeterminate
- No previous check stored for the host — change comparison unavailable on first call
- Previous result older than 90 days — baseline expired and comparison resets
- Network timeout from Cloudflare edge — may return inconclusive result
- Invalid or malformed host input — request rejected

## How this service works

Change watch for is port 69 open: runs the check, compares it with the result from your previous call for the same host (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

## Output

Returns the current open/closed status of port 69, a boolean 'changed' flag indicating whether the result differs from the previous check (stored up to 90 days), the specific fields that changed with before and after values, and a timestamp for when the state was last seen.
